What is a common risk during testing in RSI Phase 5?

Incomplete test coverage leading to undiscovered defects is a significant risk during testing in RSI Phase 5 because it can result in critical errors or failures in the final product that may go unnoticed until after deployment. This situation often arises when the testing team does not have the resources or time to test every aspect of the system thoroughly. Insufficient test coverage might mean that only a portion of the functionality is tested, leaving potential flaws in untested components.

When test cases are not comprehensively defined or executed, defects can remain in the software, ultimately impacting user experience, system reliability, and overall project success. Catching these defects late in the development cycle can be costly and time-consuming, and may require significant rework, compromising the project timeline and budget. Proper test planning and execution strategies are essential to mitigate this risk, ensuring that all critical paths and system functionalities are thoroughly examined before the product is released.
